Forget the SuperBowl Sunday fiasco. Now, Justin Timberlake has other things on his mind.

The Grammy winner is now determined to get his role as a journalist right in his movie debut Edison, reports People magazine. Apparently, he was so keen to get into the skin of a reporter that he followed Associated Press reporter Bob Porterfield.

People quotes two-time Pulitzer-winning Porterfield as saying, "He[Timberlake] was interested in learning how you retrieve these public records. Basically, I showed him how you find them, how you request them."

Timberlake made a splash at the Los Angeles county courthouse when he appeared with Porterfield. After applying to see some legal documents, he sat with Porterfield over a case filed by California Governor Arnold Schwarzenegger, actors Bruce Willis and Denzel Washington. Apparently, an electronics firm had used their likeness in some advertisements without their permission.

Porterfield said, "I thought he [Timberlake] was sharp. He seemed attentive and interested in learning this stuff. He has a real interest in developing his part. He took quite a few notes."

In Edison, Timberlake, the reporter, stumbles on a team of corrupt cops. Other actors expected to star in the movie are Kevin Spacey, Morgan Freeman and musician LL Cool J. The unit will start shooting in Canada soon.
